BROOMFIELD -- Spirited closing arguments and speculation over the significance of a California hotel room key capped off the fourth and final day of former Broomfield High wrestling coach Travis Masse's sex assault trial Thursday.

The jury was handed the case late in the afternoon and will resume deliberations this morning. Masse is charged with sexual assault on a child by a person in a position of trust.

Prosecutor Yvette Werner told the jury to examine the defendant's own words in rendering a verdict.

For the first time in the trial, she read aloud some of the explicit text messages Masse, 29, and his former student exchanged that appeared to be making references to past sexual encounters with the then-underage girl, who was a manager on his wrestling team.

Werner asked the jury to consider why the young woman, who is now 19, would come into a courtroom to testify in front of strangers about "matters so intimate and so disgusting" if they weren't true.

Defense attorney Pamela Mackey countered that the alleged victim in the case has continually changed her version of events to buttress her claim that she had been sexually assaulted by Masse.

The attorney said the dates and times her client's accuser cited for when the two were intimate were inconsistent with phone records and accounts given to police earlier.

She openly lambasted Masse for sending sexually charged text messages to the woman, and to other underage students at his school, but she said that does not equate to sexual contact.

"What he did was morally wrong," Mackey said. "But it's not sexual assault. And this is what this trial is about."

Hotel key controversy

Hanging over the proceedings Thursday was the last-minute revelation from Boulder Valley School District Superintendent Chris King that he had given the key to his eighth-floor hotel room to Masse for the final night of a weekend wrestling tournament trip to California in January 2009.

The claim is significant because Masse's accuser testified that they'd had sex in an empty room on the eighth floor of the Hotel Huntington Beach on the final night of the tournament. Authorities had been unable to find any record that Masse rented a separate room.

But District Judge Thomas Ensor wouldn't allow the prosecution to present the new information to the jury nor call King as a witness because, at this stage in the trial, he said it was too late to be introducing discovery.

At one point Thursday, the judge sharply scolded Werner for trying to reference the issue during questioning.

"Bottom line is I told you you weren't going to get this in, and you ignored me," he said, once the jury had been dismissed. "As an officer of this court, you are bound to follow the rules of this court -- whether you like it or not."

Masse wraps up testimony

Masse finished his testimony Thursday, saying he didn't have sex with his underage student at any of the out-of-town wrestling tournaments he attended nor at any other time.

Masse faces a charge of attempted unlawful sexual contact with a child in a separate case, also involving a former student. He has a trial scheduled in that case next month.

Werner, the prosecutor, struck repeatedly at the theme of deception and abdication of responsibility during her cross-examination of the former wrestling coach, who took his team to a statewide championship in 2009.

She asked him if he texted his underage students with sexually explicit messages "under the nose" of his wife, his fellow coaches and the father of the student who has accused him of sex assault.

He said he had.

"That's deceptive, right?" she asked.

"It's deceptive and highly inappropriate," Masse replied.

Jury hears texts

During closing arguments, Werner went into sordid detail about the kind of text messages Masse and the alleged victim were sending one another in the spring of 2010, which was after allegations had surfaced against Masse and he had been put on leave by Broomfield High.

One text exchange revealed the former student asking Masse for a picture of the "long lost friend I used to play with." Masse responded by sending a photo of his penis, Werner told the jury.

Masse texted the former student about wanting to have sex with her, Werner said.

After she responds, "Good, that's the way I like it," Masse writes, "I know."

"How does he know?" Werner said. "Because when they were in California, he had sexual intercourse with her."

She said Masse met his alleged victim when she was 15 and groomed her to a point where she was willing to have sex with him. Werner asked the jury why the defendant and his former student would exchange nearly 9,000 text messages in three months if there wasn't something more involved than just lustful words.

Mackey responded that there was a total lack of evidence that her client had ever inappropriately touched his former student.
